The anti-slip/adjustable design of the mirror legs and nose frame has also become necessary, ensuring that the sunglass near me will not shake at high speeds or rough terrain, making the nose bridge and ear base more comfortable.

For this sweaty sport, the ventilation design of the mirror frame is also important, such as its dedicated vents and large gaps, which are designed to prevent fogging.

Sunglasses and lenses are not simply about dimming the light. Good sports sunglasses ultimately aim to improve the wearer's athletic performance. To achieve this, sunglass near me lenses must first reach their passing line to isolate ultraviolet rays.

Ultraviolet rays are harmful to the eyes, but cannot be seen (purple light is not ultraviolet!), which means that we cannot test its UV resistance by directly wearing a pair of sunglasses. So what should we do?

Choose to trust the manufacturer and see if there are descriptions labeled as "100% UV400 blocking" or "100% UVA&UVB blocking". These two statements mean that this lens (at least claimed) can block 99.9% of ultraviolet radiation.

Our eyes don't need any ultraviolet light, but we need visible light, and it's just fine. The sunglasses near me now cannot be too light or too dark.

The transmittance parameter is often used to measure the basic performance of sunglasses, which is an international standard. We can directly ask the seller, "What is your transmittance?" or "What is your transmittance level?”
